"Post production" is the process whereby a recording is turned into something that sounds like live artists playing music. For instance, some amount of echo is added, and frequencies are emphasized to make it sound like one musician is in front of another. "Post production" does for audio what Photoshop does for images. If it is done wrong, you might think the piece was recorded in a drainage ditch or a cathedral or a beer barrel. To me these pieces sound like the band needs new microphones.
Uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuh. The whole "album" is made to sound like that. So, the "post production" is actually very precise.
